摘　　要： 随着电子设备复杂程度越来越高,电子设备的可靠性要求也越来越突出。由于影响电子式电能表不运行的因素比感应式电能表更多且更复杂,对电子式电能表的可靠性提出了更高的要求。在此以DTSF88型三相四线电子式复费率电能表为对象,介绍了电能表可靠性预计的基本方法。同时,分别采用元器件计数法和应力分析法对其进行可靠性预计,并用现场实用数据对预计结果进行了验证。可靠性预计作为一种可视化定量分析工具,为评价电子产品的可靠性提供了一种简单、实用、有效的途径。 As the electronic equipments are more and more complex,the reliability for electronic equipments is required more obviously.Since the electronic electric-energy meter is more intricacy and is more easily affected by environmental factors than the inductive meter,the higher requirement of electronic electric-energy meter for reliability is proposed.The basic methods for reliability prediction is introduced by taking DTSF88 electronic electric-energy meter as an example.The component counting method and stress analysis method were adopted for reliability prediction.The results were verified by the actual data on the spot.Reliability prediction as a quantitative analytical tool provides a very useful way to estimate the reliability for electronic equipments.
